BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to an adjusting method of a keyswitch, and more particularly, to an adjusting method applied to a keyswitch for adjusting tactile feedback.

2. Description of the Prior Art

A keyboard, which is the most common input device, could be found in variety of electronic apparatuses for users to input characters, symbols, numerals and so on. Furthermore, from consumer electronic products to industrial machine tools, they are all equipped with a keyboard for performing input operations.

In actual application, there are various kinds of keyswitches for providing different tactile feedbacks. For example, the tactile feedback may be varied by high or low triggering position between an elastic piece and a conductive electrode, long or short travel distance, required actuation force of the keyswitch, tactile or linear feedback of the keyswitch, clicky or non-clicky tactile feedback of the keyswitch, etc. That is to say, a conventional mechanical keyswitch only provides one single kind of tactile feedback without a tactile feedback adjusting function. Thus, if the user wants to experience different kinds of tactile feedbacks, the user must buy a new keyboard or replace the original keyswitches on the gaming keyboard with new keyswitches for providing another kind of tactile feedback. In such a manner, it would cause a high replacement cost, so as to greatly limit flexibility in use and operational convenience of the mechanical keyswitch.

SUMMARY OF THE INVENTION

According to the claimed invention, an adjusting method is utilized to change operational feeling of a keyboard. The keyboard includes a controller and a plurality of keyswitches, the keyboard is electrically connected with a computer. A user uses the keyboard to operate an application program executed by the computer. The plurality of keyswitches is alternatively set in one of a first hand feeling mode and a second hand feeling mode, and the controller stores a first predefined condition and a second predefined condition. The adjusting method includes detecting an operational parameter, the controller setting the plurality of keyswitches in the first hand feeling mode while the operational parameter conforms to the first predefined condition, and the controller setting the plurality of keyswitches in the second hand feeling mode while the operational parameter conforms to the second predefined condition.

The keyswitch in the first embodiment of the present invention disposes the concave and convex structures between the upper sleeve component and the lower sleeve component, the required actuation force quantity of the recovering component is varied, and the keyswitch can provide the hand feeling modes with different feedback by the same triggering travel distance; the keyswitch in the second embodiment disposes the concave and convex structures between the lower sleeve component and the substrate, the possible pressing depth of the lower sleeve component is varied, so that the pressing travel distance of the keyswitch can be adjusted for different hand feeling modes; the keyswitch in the third embodiment designs stage variation by the inclined surfaces on the outer surface of the lower sleeve component, so that the keyswitch can provide different triggering travel distances via the identical required actuation force condition; the keyswitch in the fourth embodiment disposes the resistance protrusion on position of the lower sleeve component corresponding to the electrode module, the resistance protrusion can touch or be distant from the electrode module according to the left and right turn of the lower sleeve component, which results in the hand feeling mode of non-clicky and linear feedback and the hand feeling mode of non-clicky and tactile feedback; the keyswitch in the fifth embodiment disposes the resilient arm unit on the substrate, and further disposes the resistance protrusion on the lower sleeve component corresponding to the resilient arm unit, which results in the hand feeling mode of non-clicky and linear feedback and the hand feeling mode of clicky sound and tactile feedback; the keyswitch in the sixth embodiment disposes two resistance protrusions on the lower sleeve component for the hand feeling mode of clicky and tactile feedback and the hand feeling mode of non-clicky and tactile feedback. The keyboard can utilize the adjusting component to manually or automatically switch the keyswitch into different hand feeling modes.

DETAILED DESCRIPTION

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a diagram of a keyboard 10 according to an embodiment of the present invention. FIG. 2 is an enlarged diagram of a region R shown in FIG. 1. The keyboard 10 includes a plurality of keyswitches 12 and an adjusting component 14, and the adjusting component 14 is connected to the plurality of keyswitches 12 simultaneously. A user can move the adjusting component 14 to simultaneously switch the plurality of keyswitches 12 between different hand feeling modes. The keyswitch 12 has several possible embodiments, and the user can operate the adjusting component 14 to determine how the hand feeling mode of the keyboard 10 is manually switched according to actual demand.

Please refer to FIG. 3 to FIG. 10. FIG. 3 and FIG. 4 respectively are exploded diagrams of the keyswitch 12A in different views according to a first embodiment of the present invention. FIG. 5 and FIG. 6 respectively are diagrams of the keyswitch 12A without an upper cover 18 in different hand feeling modes according to the first embodiment of the present invention. FIG. 7 and FIG. 8 respectively are sectional views of the keyswitch 12A with the upper cover 18 in different pressing modes along line A-A′ shown in FIG. 5. FIG. 9 and FIG. 10 respectively are sectional views of the keyswitch 12A with the upper cover 18 in different pressing modes along line B-B′ shown in FIG. 6.

The keyswitch 12A includes a substrate 16, the upper cover 18, an upper sleeve component 20, a lower sleeve component 22, a keycap 24 and a recovering component 26. The substrate 16 is disposed on a bottom of the keyboard 10 or a printed circuit board. The upper cover 18 is disposed on the substrate 16. The upper sleeve component 20 is disposed on the upper cover 18 in an upwardly and downwardly movable manner at a vertical direction. The lower sleeve component 22 is movably disposed between the substrate 16 and the upper cover 18, and the recovering component 26 is disposed between the substrate 16 and the lower sleeve component 22. The recovering component 26 is used to upwardly push the lower sleeve component 20. The upper sleeve component 20 includes a keycap connecting portion 28, a first bottom surface 30 and a second bottom surface 32. The keycap connecting portion 28 can be assembled with the keycap 24. The first bottom surface 30 is lower than the second bottom surface 32, which means the first bottom surface 30 can protrude from the second bottom surface 32. In addition, the lower sleeve component 22 includes a first top surface 34 and a second top surface 36, and the first top surface 34 is higher than the second top surface 36, which means the first top surface 34 is stuck out of the second top surface 36.

The substrate 16 includes a constraining pillar 38. The lower sleeve component 22 includes a main body 40 and a pushing portion 42. The main body 40 is movably disposed on the constraining pillar 38, and the pushing portion 42 stretches from a surface of the main body 40 to be partly exposed out of the substrate 16. Therefore, when the user manually presses the pushing portion 42 of each of the plurality of keyswitches 12, or utilizes the adjusting component 14 to simultaneously push the pushing portions 42 of the plurality of keyswitches 12, the main body 40 is guided by the pushing portion 42 and can be levelly rotated relative to the constraining pillar 38 at a right direction and a left direction. Besides, the upper sleeve component 20 further includes a sliding portion 44 movably disposed inside a sliding slot 46 formed on the upper cover 18. While the keycap 24 is manually pressed, the keycap 24 can be moved relative to the upper cover 18 via the sliding portion 44 upwardly and downwardly at the vertical direction; the sliding slot 46 further can be used to prevent the upper sleeve component 20 from being levelly rotated relative to the upper cover 18.

The substrate 16 further includes an electrode module 48, and the electrode module 48 includes a first electrode sheet 50 and a second electrode sheet 52. The first electrode sheet 50 is inserted into a bottom inside the substrate 16, and the second electrode sheet 52 is pasted on an inner wall of the substrate 16 and located between the first electrode sheet 50 and the lower sleeve component 22. The second electrode sheet 52 includes an elastic portion 54 movably contacting against the lower sleeve component 22. The lower sleeve component 22 can be interfered with the electrode module 48 while the lower sleeve component 22 is moved relative to the constraining pillar 38 of the substrate 16 vertically. That is to say, the elastic portion 54 of the second electrode sheet 52 can contact against and be separated from the first electrode sheet 50 in accordance with upward and downward motion of the lower sleeve component 22 for triggering the keyswitch 12A.

The lower sleeve component 22 further includes a first vertical lateral surface 56 and a second vertical lateral surface 58, and a shape of the first vertical lateral surface 56 is different form a shape of the second vertical lateral surface 58. The first vertical lateral surface 56 is connected to the first sectional inclined surface 60, the second vertical lateral surface 58 is connected to the second sectional inclined surface 62, and a distance between the first sectional inclined surface 60 and bottom of the main body 40 is greater than a distance between the second sectional inclined surface 62 and the bottom of the main body 40, which means the first sectional inclined surface 60 can be higher than the second sectional inclined surface 62. While the elastic portion 54 of the second electrode sheet 52 contacts against the first vertical lateral surface 56 or the second vertical lateral surface 58, the second electrode sheet 52 is not electrified by the first electrode sheet 50; while the elastic portion 54 contacts against the first sectional inclined surface 60 or the second sectional inclined surface 62, the second electrode sheet 52 and the first electrode sheet 50 are electrified.

The lower sleeve component 22 can be levelly rotated relative to the constraining pillar 38 of the substrate 16, so as to switch between a first angle position shown in FIG. 6 and a second angle position shown in FIG. 5. When the lower sleeve component 22 is set in the first angle position, the lower sleeve component 22 contacts against the upper sleeve component 20, the first bottom surface 30 abuts the first top surface 34, the second bottom surface 32 does not abut the second top surface 36, a gap between the substrate 16 and bottom of the lower sleeve component 22 is smaller, so that the recovering component 26 has a first length H1; in the meantime, the elastic portion 54 contacts against the first vertical lateral surface 56, as shown in FIG. 9. When the keyswitch 12A is pressed, the recovering component 26 is compressed accordingly and compression is stopped until the bottom of the lower sleeve component 22 contacts the substrate 16. The elastic portion 54 is moved from the first vertical lateral surface 56 to the first sectional inclined surface 60, and the electrode module 48 is electrified to generate a control signal of the keyswitch 12A, as shown in FIG. 10. In this hand feeling mode, the keyswitch 12A provides shorter pressing travel distance, the user exerts large force upon the keyswitch 12A for downward motion because the recovering component 26 has greater required actuation force quantity, which means heavy hand feeling is acquired.

When the lower sleeve component 22 is set in the second angle position, the lower sleeve component 22 contacts against the upper sleeve component 20, the first bottom surface 30 abuts the second top surface 36, the second bottom surface 32 abuts the first top surface 34, the gap between the substrate 16 and bottom of the lower sleeve component 22 is larger, so that the recovering component 26 has a second length H2; meanwhile, the elastic portion 54 contacts against the second vertical lateral surface 58, as shown in FIG. 7, and the second length H2 is greater than the first length H1. When the keyswitch 12A is pressed, the recovering component 26 is compressed accordingly and compression is stopped until the bottom of the lower sleeve component 22 contacts the substrate 16, the elastic portion 54 is moved from the second vertical lateral surface 58 to the second sectional inclined surface 62, and the electrode module 48 is electrified to generate the control signal of the keyswitch 12A, as shown in FIG. 8. In this hand feeling mode, the keyswitch 12A can provide longer pressing travel distance, the recovering component 26 has smaller required actuation force quantity, and the user exerts large force upon the keyswitch 12A for downward motion.

Thus, the first embodiment of the present invention disposes the first bottom surface 30 and the second bottom surface 32 on the bottom of the upper sleeve component 20, disposes the first top surface 34 and the second top surface 36 corresponding to the bottom surfaces 30 and 32 on top of the lower sleeve component 22, the upper sleeve component 20 is constrained by the upper cover 18 and cannot be rotated levelly. Rotation of the lower sleeve component 22 can change the gap between the upper sleeve component 20 and the lower sleeve component 22, an initial height of the lower sleeve component 22 relative to the substrate 16 is adjustable, so that the recovering component 26 has dissimilar required actuation force quantity for providing different hand feeling modes. An outer surface of the lower sleeve component 22 has the first vertical lateral surface 56 and the first sectional inclined surface 60 matched with the first angle position, and further has the second vertical lateral surface 58 and the second sectional inclined surface 62 matched with the second angle position, hence the keyswitch 12A can provide identical trigger travel distance at any angle position.

Please refer to FIG. 11 to FIG. 18. FIG. 11 and FIG. 12 respectively are exploded diagrams of the keyswitch 12B in different views according to a second embodiment of the present invention. FIG. 13 and FIG. 14 respectively are diagrams of the keyswitch 12B without the upper cover 18 in different hand feeling modes according to the second embodiment of the present invention. FIG. 15 is a sectional view of the keyswitch 12B with the upper cover 18 along line C-C′ shown in FIG. 13. FIG. 16 is a sectional view of the keyswitch 12B with the upper cover 18 along line D-D′ shown in FIG. 13. FIG. 17 is a sectional view of the keyswitch 12B with the upper cover 18 along line E-E′ shown in FIG. 14.

The lower sleeve component 22′ is movably disposed between the substrate 16′ and the upper cover 18, and the recovering component 26 is movably disposed between the substrate 16′ and the lower sleeve component 22′. The lower sleeve component 22′ includes a first bottom surface 68 and a second bottom surface 70, and the second bottom surface 70 is sunk in the first bottom surface 68, which means the first bottom surface 68 is lower than the second bottom surface 70. The recovering component 26 is used to upwardly push the lower sleeve component 20. The upper sleeve component 20 includes the keycap connecting portion 28, and the keycap connecting portion 28 can be assembled with the keycap 24.

The substrate 16′ includes the constraining pillar 38. The lower sleeve component 22′ includes the main body 40 and the pushing portion 42, the main body 40 is movably disposed on the constraining pillar 38, and the pushing portion 42 stretches from the surface of the main body 40 to be partly exposed out of the substrate 16′. Therefore, when the user manually presses the pushing portion 42 of each of the plurality of keyswitches 12, or utilizes the adjusting component 14 to simultaneously push the pushing portions 42 of the plurality of keyswitches 12, the main body 40 is guided by the pushing portion 42 and can be levelly rotated relative to the constraining pillar 38. Moreover, the upper sleeve component 20 further includes the sliding portion 44 movably disposed inside the sliding slot 46 formed on the upper cover 18. While the keycap 24 is pressed, the keycap 24 can be moved relative to the upper cover 18 via the sliding portion 44 upwardly and downwardly at the vertical direction; the sliding slot 46 further can be utilized to prevent the upper sleeve component 20 from being levelly rotated relative to the upper cover 18.

The substrate 16′ further includes the electrode module 48, and the electrode module 48 includes the first electrode sheet 50 and the second electrode sheet 52. The first electrode sheet 50 is inserted into the bottom inside the substrate 16, and the second electrode sheet 52 is pasted on the inner wall of the substrate 16 and located between the first electrode sheet 50 and the lower sleeve component 22′. The second electrode sheet 52 includes the elastic portion 54 movably contacting against the lower sleeve component 22′. The lower sleeve component 22′ can be interfered with the electrode module 48 while the lower sleeve component 22′ is moved relative to the constraining pillar 38 of the substrate 16 vertically. That is, the elastic portion 54 of the second electrode sheet 52 can contact against and be separated from the first electrode sheet 50 in accordance with upward and downward motion of the lower sleeve component 22′ for an aim of triggering the keyswitch 12B.

The lower sleeve component 22′ further includes the first vertical lateral surface 56 and the second vertical lateral surface 58, and the shape of the first vertical lateral surface 56 is different form the shape of the second vertical lateral surface 58. The first vertical lateral surface 56 is connected to the first sectional inclined surface 60, the second vertical lateral surface 58 is connected to the second sectional inclined surface 62, and the distance between the first sectional inclined surface 60 and the bottom of the main body 40 is greater than the distance between the second sectional inclined surface 62 and the bottom of the main body 40, which means the first sectional inclined surface 60 can be higher than the second sectional inclined surface 62. While the elastic portion 54 of the second electrode sheet 52 contacts against the first vertical lateral surface 56 or the second vertical lateral surface 58, the second electrode sheet 52 is not electrified by the first electrode sheet 50; while the elastic portion 54 contacts against the first sectional inclined surface 60 or the second sectional inclined surface 62, the second electrode sheet 52 and the first electrode sheet 50 are electrified.

The lower sleeve component 22′ can be levelly rotated relative to the constraining pillar 38 of the substrate 16, so as to switch between the first angle position shown in FIG. 13 and the second angle position shown in FIG. 14. When the lower sleeve component 22′ is set in the first angle position, the second bottom surface 70 of the lower sleeve component 22′ does not align with the first top surface 64 of the substrate 16′; if the keyswitch 12B is pressed, the lower sleeve component 22′ can be moved downward until the first bottom surface 68 abuts the first top surface 64, the elastic portion 54 is moved from the second vertical lateral surface 58 to the second sectional inclined surface 62, and the electrode module 48 is electrified to trigger the keyswitch, as shown in FIG. 15 and FIG. 16, and upward and downward motion of the lower sleeve component 22′ has a first travel distance S1.

The keyswitch 12B of the second embodiment disposes the first top surface 64 and the second top surface 66 with stage variation on the substrate 16′, and disposes the first bottom surface 68 and the second bottom surface 70 on the lower sleeve component 22′. While the lower sleeve component 22′ is switched between the first angle position and the second angle position, the gap between the lower sleeve component 22′ and the upper sleeve component 20 is not changed, and the lower sleeve component 22′ may only contact against the first top surface 64 or simultaneously contact against the first top surface 64 and the second top surface 66 when the lower sleeve component 22′ is moved downwardly. Therefore, the second embodiment can adjust a possible pressing depth or the pressing travel distance of the keyswitch 12B by rotation of the lower sleeve component 22′.

Please refer to FIG. 19 to FIG. 24. FIG. 19 and FIG. 20 respectively are exploded diagrams of the keyswitch 12C in different views according to a third embodiment of the present invention. FIG. 21 and FIG. 22 respectively are diagrams of the keyswitch 12C without the upper cover 18 in different hand feeling modes according to the third embodiment of the present invention. FIG. 23 is a sectional view of the keyswitch 12C with the upper cover 18 along line G-G′ shown in FIG. 21. FIG. 24 is a sectional view of the keyswitch 12C with the upper cover 18 along line H-H′ shown in FIG. 22.

The keyswitch 12C includes the substrate 16, the upper cover 18, the upper sleeve component 20, the lower sleeve component 22″, the keycap 24 and the recovering component 26.

The recovering component 26 is used to move the lower sleeve component 20 upwardly. The upper sleeve component 20 includes the keycap connecting portion 28, the first bottom surface 30 and the second bottom surface 32. The keycap connecting portion 28 can be assembled with the keycap 24.

The substrate 16 includes the constraining pillar 38. The lower sleeve component 22″ includes the main body 40 and the pushing portion 42. The main body 40 is movably disposed on the constraining pillar 38, and the pushing portion 42 stretches from the surface of the main body 40 to be partly exposed out of the substrate 16. Therefore, when the user manually presses the pushing portion 42 of each of the plurality of keyswitches 12, or utilizes the adjusting component 14 to simultaneously push the pushing portions 42 of the plurality of keyswitches 12, the main body 40 is guided by the pushing portion 42 and can be levelly rotated relative to the constraining pillar 38. Besides, the upper sleeve component 20 further includes the sliding portion 44 movably disposed inside the sliding slot 46 formed on the upper cover 18. While the keycap 24 is pressed, the keycap 24 can be moved relative to the upper cover 18 via the sliding portion 44 in an upwardly and downwardly movable manner at the vertical direction; the sliding slot 46 further can be used to prevent the upper sleeve component 20 from being levelly rotated relative to the upper cover 18.

The substrate 16 further includes the electrode module 48, and the electrode module 48 includes the first electrode sheet 50 and the second electrode sheet 52. The first electrode sheet 50 is inserted into the bottom inside the substrate 16, and the second electrode sheet 52 is pasted on the inner wall of the substrate 16 and located between the first electrode sheet 50 and the lower sleeve component 22″. The second electrode sheet 52 includes the elastic portion 54 movably contacting against the lower sleeve component 22″. The lower sleeve component 22″ can be interfered with the electrode module 48 while the lower sleeve component 22″ is moved relative to the constraining pillar 38 of the substrate 16 vertically. Thus, the elastic portion 54 of the second electrode sheet 52 can contact against and be separated from the first electrode sheet 50 in accordance with upward and downward motion of the lower sleeve component 22″ for triggering the keyswitch 12C.

The lower sleeve component 22″ further includes the first vertical lateral surface 56 and the second vertical lateral surface 58, and the shape of the first vertical lateral surface 56 is different form the shape of the second vertical lateral surface 58.

While the elastic portion 54 of the second electrode sheet 52 contacts against the first vertical lateral surface 56 or the second vertical lateral surface 58, the second electrode sheet 52 is not electrified by the first electrode sheet 50; while the elastic portion 54 contacts against the first sectional inclined surface 60 or the second sectional inclined surface 62, the second electrode sheet 52 and the first electrode sheet 50 are electrified.

Please refer to FIG. 42. FIG. 42 is a flow chart of changing operational hand feeling of the keyboard 10 according to the embodiment of the present invention. The keyboard 10 is electrically connected to an external computer (not shown in figures), and the user can use the keyboard 10 to operate an application program executed by the computer. The plurality of keyswitches 12 of the keyboard 10 can be alternatively set in the first hand feeling mode or the second hand feeling mode; additionally, a controller 82 of the keyboard 10 can pre-store a first predefined condition and a second predefined condition. With regard to the adjusting method of changing the operational hand feeling of the keyboard 10, step S420 is executed first that the controller 82 is actuated to detect an operational parameter from the computer or the keyboard 10. Then, step S422 is executed to determine whether the operational parameter conforms to the predefined condition. As the first predefined condition is conformed, step S424 is executed that the controller 82 sets the plurality of keyswitches 12 in the first hand feeling mode; as the second predefined condition is conformed, step S426 is executed that the controller 82 sets the plurality of keyswitches 12 in the second hand feeling mode. Besides, the plurality of keyswitches 12 can be kept in the current hand feeling mode when the operational parameter does not conform to the first predefined condition and the second predefined condition.

The operational parameter can be various types, and its variation is not limited to the following embodiments, which depends on design demand. For example, the operational parameter can be a category of the application program executed by an active window of the computer, such as document program and game program. The first predefined condition may define the document program (such like Microsoft Word) belonging to the first category, and the second predefined condition may define the game program (such like Blizzard Overwatch) belonging to the second category. Therefore, while the application program executed by the computer belongs to the first category, the plurality of keyswitches 12 can be switched to the first hand feeling mode; while the application program executed by the computer belongs to the second category, the plurality of keyswitches 12 can be switched to the second hand feeling mode. The various hand feeling modes may be selected from a group consisted of working travel distance, pressing feedback, triggering depth, clicky sound, clicky resistance, and a combination thereof. The user can adjust foresaid factors in the hand feeling mode in accordance with the application program.

The category of the application program can be identified by a name or a usage frequency of the application program. The user may classify the application programs in the computer by inputting the name, or the adjusting method may detect the usage frequency of the application program for classification. The category of the application program can be set according to an input command or statistics information collected by the computer. The user may decide the document program belonging to the first category and the game program belonging to the second category, and input a command to store related information into the computer. In addition, the computer may collect statistics information about operation, such as a press frequency of the plurality of keyswitches, a number of pressing within a predefined period, or a turn-on period of a display, and determine the category of the application program according to analysis of the statistics information.

Further, the operational parameter can be a category of some predefined usage situations of the computer. The computer may have some usage situations, such as usage time, a running period, or temperature of the computer. The first predefined condition may define daytime or the long-term running period or high temperature belonging to a first usage situation. The second predefined condition may define nighttime or the short-term running period or low temperature belonging to a second usage situation. The plurality of keyswitches 12 can be switched to the first hand feeling mode or the second hand feeling mode in response to the current usage situation of the computer. Examples of the predefined usage situation are not limited to the above-mentioned embodiments, and depend on actual demand.

The operational parameter further can be set as press frequency of the plurality of keyswitches 12. The first predefined condition may define that the press frequency of the plurality of keyswitches 12 is greater than a predefined value, therefore when the press frequency of the plurality of keyswitches 12 is greater than the predefined value, such as the keyswitch 12 being pressed rapidly in high frequency, the plurality of keyswitches 12 is switched to the first hand feeling mode. The second predefined condition may define that the press frequency of the plurality of keyswitches 12 is smaller than the predefined value, when the press frequency of the plurality of keyswitches 12 is smaller than the predefined value, the keyswitch is pressed slowly and occasionally, and the plurality of keyswitches 12 is switched to the second hand feeling mode.

The operational parameter further can be set as a number of pressing the plurality of keyswitches 12 within a predefined period. For instance, the first predefined condition may define that the number of pressing within the predefined period is greater than the predefined value, when the number of pressing within the predefined period is greater than the predefined value, the plurality of keyswitches 12 is switched to the first hand feeling mode; the second predefined condition may define that the number of press within the predefined period is smaller than the predefined value, when the number of pressing within the predefined period is smaller than the predefined value, the plurality of keyswitches 12 is switched to the secondhand feeling mode. Thus, the operational parameter can indicate a weary degree of someone who operates the keyboard 10. The user is tired when the press frequency and/or the number of pressing the keyswitches 12 are decreased within the predefined period. Increasing of the press frequency and the number of pressing the keyswitches 12 within the predefined period may represent the user is energetic.

Switching of the keyswitch 12 can be manually operated by the user, as shown in FIG. 1, holes on the adjusting component 14 are respectively engaged with the pushing portions 42 of the plurality of keyswitches 12, the user can push the adjusting component 14 to simultaneously switch the plurality of keyswitches 12 into the first hand feeling mode or the second hand feeling mode. Additionally, the keyboard 10 may have a driving device 84, such as an electric motor. When the controller 82 detects that the operational parameter conforms to the first predefined condition or the second predefined condition, the user can start off the driving device 84 to move the adjusting component 14, so as to simultaneously switch the plurality of keyswitches 12 into one of the first hand feeling mode and the second hand feeling mode.

In conclusion, the keyswitch in the first embodiment of the present invention disposes the concave and convex structures between the upper sleeve component and the lower sleeve component, the required actuation force quantity of the recovering component is varied, and the keyswitch can provide the hand feeling modes with different feedback by the same triggering travel distance; the keyswitch in the second embodiment disposes the concave and convex structures between the lower sleeve component and the substrate, the possible pressing depth of the lower sleeve component is varied, so that the pressing travel distance of the keyswitch can be adjusted for different hand feeling modes; the keyswitch in the third embodiment designs stage variation by the inclined surfaces on the outer surface of the lower sleeve component, so that the keyswitch can provide different triggering travel distances via the identical required actuation force condition; the keyswitch in the fourth embodiment disposes the resistance protrusion on position of the lower sleeve component corresponding to the electrode module, the resistance protrusion can touch or be distant from the electrode module according to the left and right turn of the lower sleeve component, which results in the hand feeling mode of non-clicky and linear feedback and the hand feeling mode of non-clicky and tactile feedback; the keyswitch in the fifth embodiment disposes the resilient arm unit on the substrate, and further disposes the resistance protrusion on the lower sleeve component corresponding to the resilient arm unit, which results in the hand feeling mode of non-clicky and linear feedback and the hand feeling mode of clicky sound and tactile feedback; the keyswitch in the sixth embodiment disposes two resistance protrusions on the lower sleeve component for the hand feeling mode of clicky and tactile feedback and the hand feeling mode of non-clicky and tactile feedback.
